To assess visual function in patients with irregular cornea who do not tolerate gas permeable (GP) corneal contact lenses and are fitted with GP scleral contact lenses (Rose K2 XL).
In this prospective study, we analyzed 15 eyes of 15 patients who did not tolerate GP corneal contact lenses and were fitted with scleral contact lenses (Rose K2 XL). We assessed visual function using visual acuity and the visual function index (VF-14); we used the VF-14 as an indicator of patient satisfaction. The measurements were taken with the optical correction used before and 1 month after the fitting of the Rose K2 XL contact lenses. We also recorded the number of hours lenses had been worn over the first month.
Using Rose K2 XL contact lenses, visual acuity was 0.06±0.07 logMAR. In all cases, visual acuity had improved compared with the measurement before fitting the lenses (0.31±0.18 logMAR; P=0.001). VF-14 scores were 72.74±12.38 before fitting of the scleral lenses, and 89.31±10.87 after 1 month of lens use (P=0.003). Patients used these scleral lenses for 9.33±2.99 comfortable hours of wear.
Both visual acuity and VF-14 may improve after fitting Rose K2 XL contact lenses in patients with irregular corneas. In addition, in our patients, these lenses can be worn for a longer period than GP corneal contact lenses.
评估不耐受透气性（GP）角膜接触镜而佩戴GP巩膜接触镜（Rose K2 XL）的不规则角膜患者的视觉功能。
在这项前瞻性研究中，我们分析了15例不耐受GP角膜接触镜而佩戴巩膜接触镜（Rose K2 XL）患者的15只眼。我们使用视力和视觉功能指数（VF - 14）评估视觉功能；我们将VF - 14作为患者满意度的指标。测量在佩戴Rose K2 XL接触镜之前和之后1个月使用的光学矫正情况下进行。我们还记录了第一个月内镜片的佩戴时长。
使用Rose K2 XL接触镜时，视力为0.06±0.07 logMAR。在所有病例中，与佩戴镜片前的测量值（0.31±0.18 logMAR；P = 0.001）相比，视力均有所提高。巩膜镜佩戴前VF - 14评分为72.74±12.38，镜片使用1个月后为89.31±10.87（P = 0.003）。患者佩戴这些巩膜镜的舒适时长为9.33±2.99小时。
对于不规则角膜患者，佩戴Rose K2 XL接触镜后视力和VF - 14可能都会改善。此外，在我们的患者中，这些镜片的佩戴时间比GP角膜接触镜更长。
